Hex bytes when sending A1 ON: Host = PC, Device = CM11A

Host   --> 04 66   (Send address A1)
Device --> 6a      (Receive checksum of 04 and 66)
Host   --> 00      (OK, send it out on the power line)
Device --> 55      (CM11A ready for next command)
Host   --> 06 62   (Send function A ON)
Device --> 68      (Receive checksum of 06 and 62)
Host   --> 00      (OK, send it out on the power line)
Device --> 55      (CM11A ready for next command)
